      "对生产环境进行实时监控，以便在出现问题时快速回滚。"
    ],
    "correctAnswerIndex": 0,
    "explanation": "持续集成（Continuous Integration）的核心在于“频繁集成”和“自动化验证”。它要求开发人员频繁地将代码合并到共享的主分支，每次合并后都会触发自动化的构建和测试流程，目的是尽早发现并解决集成错误，确保主分支的稳定性。",
    "source": "文档中「1. 什么是持续集成（CI）与持续部署（CD）」部分",
    "hint": "CI 的定义是“开发人员将代码频繁地合并到主分支中，并通过自动化的构建与测试来验证...”"

      "管理项目的第三方库依赖，确保构建环境一致性。",
      "模拟用户操作，进行端到端的功能验证。",
      "进行静态代码分析，及时发现潜在的代码质量问题，如代码风格和复杂度。",
      "自动化地将应用打包为 Docker 容器，为部署做准备。"
    ],
    "correctAnswerIndex": 2,
    "explanation": "文档明确指出，CI 不仅关注功能，还应注重代码质量。SonarQube、Checkstyle 这类工具属于静态代码分析工具，它们可以在不运行代码的情况下检查代码的风格、复杂度、潜在错误等，帮助团队维持高水平的代码质量并减少技术债务。",
    "source": "文档中「2.3 代码质量检查」部分",
    "hint": "这类工具关注的是代码本身的可读性、复杂度和潜在缺陷，而非其运行时的功能。"

    "options": [

    "correctAnswerIndex": 1,
    "explanation": "蓝绿部署是一种旨在降低部署风险、实现快速回滚的策略。它维护两个相同的生产环境（蓝色和绿色），只有一个环境对外提供服务。部署新版本时，在离线环境中完成部署和测试，然后将流量切换过去。如果新版本出现问题，可以立即将流量切回旧环境，从而将对用户的影响降到最低。",

      "设定严格的拉取请求（PR）合并策略，加强代码审查。",
      "使用 Docker 等容器化技术，并结合 Terraform 等工具实现基础设施即代码。",
      "采用灰度发布策略，逐步扩大新版本的用户范围。"
    ],
    "correctAnswerIndex": 2,
    "explanation": "文档在挑战章节中明确指出了解决环境一致性问题的方案：1. 使用容器化技术（如Docker）将应用及其所有依赖打包在一起，确保在任何地方运行环境都相同。2. 通过基础设施即代码（如Terraform）自动化地管理和配置基础设施，消除手动配置带来的差异。",
    "source": "文档中「5.1 环境一致性问题」部分",

    "correctAnswerIndex": 2,
    "explanation": "文档中明确定义了不同测试类型的职责。端到端测试（End-to-end testing）的作用正是模拟真实用户的操作流程，从用户界面一直到底层数据，验证整个系统的功能是否符合预期，确保应用在用户实际使用场景下能够正常工作。",
    "source": "文档中「2.2 编写自动化测试」部分",
    "hint": "这种测试关注的是从用户的视角看，整个应用流程是否通畅。"

    "explanation": "“频繁的代码提交”是持续集成（CI）的关键要素，是CI流程的起点。而持续部署（CD）是在CI成功的基础上，进一步将通过测试的代码自动化地发布到生产环境，其关键要素包括自动化发布、对生产环境的监控以及从用户处获得快速反馈。",
    "source": "文档中「1.1 持续集成的关键要素」与「1.2 持续部署的关键要素」部分",

    "correctAnswerIndex": 0,
    "explanation": "“小步快跑，频繁集成”是持续集成的核心最佳实践之一。通过小批量、高频率地提交和集成代码，可以更快地发现和定位问题，因为每次变更的范围很小。这大大降低了单次集成的复杂度和解决冲突的难度，从而降低了风险。",
